Data_Out_Lower
Access: Read
Data_Out_Upper
Access: Read
Data Type: Sixteen bit word.
USAGE: Data can be written to these registers from the system self test, or the pixel
dump command. The data can be read out 0x0d, or 0x0d first, then 0x0c.

Pixel Dump command
Once the pixel dump command is given, the sensor
writes the address and the value for the first pixel into
the Data_Out_Upper and Data_Out_Lower registers.
The MSB of Data_Out_Lower is the status bit for the
data. If the bit is high, the data are NOT valid. Once the
MSB is low, the data for that particular read are valid
and should be saved. The pixel address and data will
then be incremented on the next frame. Once the pixel
dump is complete, the PixDump bit in register 0x0a
should be set to zero. To obtain an accurate image, the
LED needs to be turned on by changing the sleep mode
of the configuration register 0x0a to always awake.
